Shaw IHudson, WestMedway, Mass.) assignor to Draper Corporation, Hopedale, Mass, a corporation of. Maine Application April 3,1943, Serial No. 481,731 f rolaims. (c1. 139 208) The present invention relates to shuttle for use in fly shuttle looms and'as illustrated herein ree I lates more particularly to shuttles of the type wherein a pivoted spindle supports a filling car; rying bobbin or cop.

Pivoted spindles of the type abovereferred to must be accurately alined with the shuttle eye and such .alinement must be maintained during operation of the loom if filling breakage is to be avoided.- Various means for alining the spindle with the shuttle eye have heretofore been pro:

posed. Some of these proposals have been em bodied in constructions which'were effective to maintain the desired alinement during operation of the loom but in most cases it was necessary to move the spindle out of running-positionto permit adjustment of a stop member. This was objectionable since it was difiicultto adjust thestop member accuratelyto aline the spindle without making repeated adjustments. j One object of the present invention is to provide ashuttlewith improved means for quickly and. easily aliningthe shuttle supporting spindle in itsproper operating position in the shuttle.

To this end andas illustrated, the stop member is providedwith a tapered portion engaging the bare portion of the spindle and which stop means can be adjustedfrom the outside of the shuttle while the spindle remains in operating position. By the use of this construction, alinement of the spindle is facilitated and a positive stop is provided which may not accidently be displaced from adjusted position.

With the above and other objects. and features in view, the invention will now be described with particular reference to the accompanying drawing in which:

Fig. 1 is a plan view of the end of a shuttle embodying the present invention;

Fig. 2 is a view in section taken along the line IIII of Fig. 1;

Fig. 3 is a view in section taken along the line III--III of Fig. 2; and

Fig. 4 is a perspective view on a somewhat enlarged scale of the spindle and the adjusting means therefor.

The shuttle shown in the drawing comprises a shuttle body I!) having a recess I2 thereinfor plate 24 which maintains the spindle in either its operating positionor in upturned position to receive a bobbin. Thespring plate 24 is secured in placein the shuttle'bya holding screw 26; The shuttle is also provided with a usual U shaped holder member 28 for holding the bobbin or cop against longitudinal movement when the bobbin supporting spindle i8 is in operating position.

The holdermember 28 is received in rece'sses;

formed-in the walls of the shuttle andis held in position by apin 30. 1

. The parts of the shuttle described abovear'e of usual construction. The "present shuttle, however, is provided with an improved stop member 32 which is arranged to engage a tail or abutment 34-formedas a part of the bare portion l6 of the spindle l8. As'shown most clearly in'Fig's.

- 2, 3 and 4, the tail is formed as a downward engagethe stop member 32;

The stop member 32 is provided with a tapered receivin a filling carrier or bobbin. The shuttle body It) is also provided with a cavity I4 in which the bare portion [6 of a bobbin supporting spindle I8 is mounted.

The bare portion I6 is pivotally supported on a bolt, 20 insuch amanner that the heel portion 22 of the spindle is engaged by one end of a spring extension of the bare portion l6 and is provided with an 'inclinedsurface 36 which is arranged to portion 38 and threaded ends- 43 and, the;

threaded 'end 42' being provided with a screw" driver "slot M. The stop 32' is threaded'lnto a hole formed in the shuttle body I!) and, as'illus trate'd. is located below the pivot boltZll. The' inclined surface 38 on the tail 34 fits againstthe tapered portion 38 of the stop 32. Thus, the position of the spindle 18 can readily be adjusted by turning the stop member 32. .As the tapered portion 38 isscrewed further. into the shuttle, the spindle I8 is rotated in a clockwise turning the stop 32 in the other direction, the

spindle will rotate in a counterclockwise direc tion to aline the spindle. Since the tapered portion 38 of the stop engages the tail 34 over. substantially its entire length, the portion 38 has a substantial bearing on thetail 34 and wear on both of these parts is reduced to a minimum.

The screw driver slot 44 is accessible from the outside of the shuttle and adjustment of the stop member 32 can be ,made when the spindle I8 is in operating position. Thus, the stop member 32 is turned until the spindle .I8 is alined in the shuttle with the shuttle eye. The stop member 32 will remain in adjusted position without the use of any locking means and cannot readily be accidently displaced out of adjusted position.
